Bad service from Builders Helderberg

We bought a Kwikot geyser from Builders Helderberg, the geyser arrived I told the delivery guys to place in it a designated area. The plumbers came and opened the bag and we saw the geyser was damaged. Looks like someone gashed it with a axe. I called the store and asked them for a replacement ASAP as the plumbers were at my place waiting, they said the geyser can only be delivered first thing the following morning. It's currently after 12 the next morning and the geyser is not here, I called the store and they transferring me from one department to another. They now say they waiting for a driver which means it wasn't dispatched 'first thing' as they stated the previous day. The job could've been done already. I am profusely upset!
